as seen in the AMCC manuals.

c0b46d8ead net: Fix problem with 405EZ ethernet interrupt
On 405EZ the RX-/TX-interrupts are coalesced into one IRQ bit in the
UIC. We need to acknowledge the RX-/TX-interrupts in the
SDR0_ICINTSTAT reg as well.

This problem was introduced with commit
d1631fe1 [ppc4xx: Consolidate PPC4xx UIC defines]

d1c3b27525 ppc4xx: Big cleanup of PPC4xx defines
This patch cleans up multiple issues of the 4xx register (mostly
DCR, SDR, CPR, etc) definitions:

- Change lower case defines to upper case (plb4_acr -> PLB4_ACR)
- Change the defines to better match the names from the
  user's manuals (e.g. cprpllc -> CPR0_PLLC)
- Removal of some unused defines

Please test this patch intensive on your PPC4xx platform. Even though
I tried not to break anything and tested successfully on multiple
4xx AMCC platforms, testing on custom platforms is recommended.

317734966e Dual-license IBM code contributions
It was brought to our attention that U-Boot contains code derived from the
IBM OpenBIOS source code originally provided with some of the older PowerPC
4xx development boards.  As a result, the original license of this code has
been carried in the various files for a number of years in the U-Boot project.

IBM is dual-licensing the IBM code contributions already present in U-Boot
under either the terms of the GNU General Public License version 2, or the
original code license already present.

0544c63681 ppc4xx: Fixed compilation warning in 4xx_enet.c
This patch fixes a compilation warning for some Ethernet PHY-less
PPC4xx platforms (440SPE based ones) and a potential compilation
error for 440SP platforms (use of undefined 'ethgroup' variable).
In the original code and in case of 440SPE platforms, 'ethgroup'
is initialized to -1 and never modified.  Later in the function,
within an #ifdef statement, an 'if statement' executes code only
if 'ethgroup' is set to 4, therefore it is harmless to avoid
executing the 'if statement' by removing the CONFIG_440SPE from
the affected #ifdefs.  In case of 440SP platforms  with on-board
Ethernet PHY, 'ethgroup' is undefined but used (there are not such
platforms in the repository yet). All other architectures are not
affected by this change.

0c24dec550 ppc4xx/net: Fix MDIO clock setup
This patch fixes MDIO clock setup in case when OPB frequency is 100MHz.
Current code assumes that the value of sysinfo.freqOPB is 100000000
when OPB frequency is 100MHz. In reality it is 100000001. As a result
MDIO clock is set to incorrect value, larger than 2.5MHz, thus violating
the standard. This in not a problem on boards equipped with Marvell PHYs
(e.g. Canyonlands), since those PHYs support MDIO clocks up to 8.3MHz,
but can be a problem for other PHYs (e.g. Realtek ones).

d3f871482f drivers/net/: get mac address from environment
The environment is the canonical storage location of the mac address, so
we're killing off the global data location and moving everything to
querying the env directly.
